Jenareta Seti Ndicho Kiyi Equipment yeHydropower Station

Simba ndiro hwaro hwezvinhu zvekusimudzira magariro uye rutsigiro uye simba rekukura kwehupfumi hwenyika.Simba harisi chete rine hukama nekukura kwevanhu, asi rinoitawo basa risingadzoreki mukusimudzira magariro nehupfumi.Muchimiro chemazuva ano chekushandiswa kweMagetsi muChina, simba rezvicherwa richiri kutonga, uye kupokana pakati pesimba shoma uye kuwedzera kuri kuda kuri kuwedzera, izvo zvave bhodhoro rinotadzisa budiriro yemagariro nehupfumi.Mumamiriro ezvinhu aya, semhando yesimba rinodzokororwa, hydropower yakapinda munhoroondo nhanho uye yakagara yakakosha chinzvimbo.Kushandiswa kwesimba repasi rose kunotarisirwa kuwedzera ka1.5 kubva pa1174.3 bhiriyoni matani muna 2010 kusvika 175.17 bhiriyoni matani muna 2035. Kushandiswa kwemafuta efossil iko zvino kwava kuita 90 muzana.Shanduko muzviwanikwa zvechisikigo uye simba rakachena dzinofanirwa kuongororwa zvakare nekuda kwemafuta asingadzokerike efossil uye maitiro azvo ezvakatipoteredza uye hutano.Simba reHydropower rinotora 15% yemagetsi epasi rose uye ndiro tsime guru resimba rinodzokororwa uye rinoenderera mberi.

Iyo turbine ndiyo moyo wechero hydropower station, ichishandura simba rinogona kuitika remvura kuita magetsi emagetsi.Iyo hydro-jenareta seti ndiyo yakakosha midziyo yehydropower station, uye kushanda kwayo kwakachengeteka ndiyo vimbiso yakakosha yekuona yakachengeteka, yemhando yepamusoro uye yehupfumi kugadzirwa kwemagetsi uye kupihwa kwemagetsi ehydropower station.Iyo yakanangana neiyo yakachengeteka uye yakagadzikana mashandiro egidhi remagetsi, uye inosarudza hupfumi uye hwemagariro mabhenefiti eiyo hydropower station.Mhedzisiro yacho inoratidza kuti kugadzikana kwe hydraulic kunokonzerwa ne turbulent pulsation yeturbine chinhu chakakosha kuona kugadzikana kwekushanda kweturbine.Muchokwadi, mukushanda kweiyo hydropower units, vibration inowanzokonzerwa nemagetsi uye zvikonzero zvemagetsi mukuwedzera kune kudengenyeka kunokonzerwa nekusagadzikana kwehydraulic.Zvinoenderana nenhamba, inenge 80% yekutadza kana tsaona dzemagetsi emagetsi emagetsi anoratidzwa mumasaini ekudengenyeka.Naizvozvo, zvakakosha zvikuru kudzidza nzira yekuongorora kukanganisa kweiyo hydropower unit uye kuona zvine hungwaru kuvhiyiwa kukanganisa kwehydropower unit yekuvandudza kutadza kuongororwa kweiyo hydropower unit muChina nekudzikisa gap nehunyanzvi hwakafanana kunze kwenyika.

Nekuwedzera kwehuwandu uye chimiro chechiyero chehydro-jenareta unit, kugadzikana kwekushanda kweyuniti kwave dambudziko rekukurumidzira resainzi uye engineering kuti ridzidzwe.Kuongorora kwakadzama kweiyo vibration meshini yehydro-jenareta unit inogona kuve nechokwadi chekuvimbika kwayo kwekushanda uye nekugona kudzivirira kana kuderedza kukuvadza kunokonzerwa nekutadza kwekudengenyeka kune iyo unit.Izvo zvakakosha zvakakosha kuti unzwisise kuzunguzika kwehydraulic turbine.

Zvikonzero zvikuru zve mechanical vibration ndezvi:

Kurongeka kusina kunaka kwegomba guru pane flange, kusunungura kwekubatanidza kana kusunungurwa kwezvikamu zvekugadzirisa zvinotungamirira kukudengenyeka kwegomba guru rakaputsika mutsara;

Kudedera kwechikamu chinotenderera cheyuniti nekuda kwekusaenzana kukuru, kukotama kana kudonha kubva pazvikamu;

Kuzununguka kunokonzerwa nekukweshana pakati pechikamu chinotenderera uye chikamu chakamisikidzwa cheyuniti, gaka rakakura pakati pegwenzi rinotakura gwenzi, gwenzi risina kuenzana rinotakura, musoro wakasununguka uye zvichingodaro.

Kudengenyeka kunokonzerwa nekukanganisa kwemuchina kana kukanganisa kune zvakajairika maitiro.Iyo vibration frequency ndeye frequency kutendeuka kana kuwanda frequency kutendeuka, uye iyo isina kuenzana simba ndeye radial kana yakachinjika.

Electromagnetic vibration inogona kukamurwa kuita marudzi maviri: kutenderera frequency vibration uye polar frequency vibration.Izvo zvinokonzerwa nemagetsi zvinokonzeresa frequency kupinduka vibration zvakanyanya kupfupika kutenderera kwe rotor mhepo, kusaenzana kwemhepo gap reyakagadziriswa rotor, asymmetric kushanda uye kurongeka kwakashata kwemagineti mapango, zvichikonzera magineti yedunhu asymmetry, magineti tension kusaenzana uye vibration.Stator musimboti kusunungura kunokonzeresa 100Hz yakanyanyisa frequency vibration.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yakavambwa muna 2006, inogadzira dhiziri jenareta muChina, iyo inobatanidza dhizaini, kugovera, kutumira uye kugadzirisa kwedhiziri jenareta seti.Chigadzirwa chinofukidza Cummins, Perkins, Volvo , Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai etc. nesimba siyana 20kw-3000kw, uye kuva yavo OEM fekitari uye tekinoroji centre.
